, useful improvements in syringes, and is fully described and explainedin the speciiication and shown in the accompanying drawings, in whichzFigure l is an elevation of my improved syringe, and Fig. 2 is alongitudinal section therethrough.

Referring to the drawings, Buis a tubular body provided with a lateralextension l. The front end of the body 3 is normally closed by a head 5of generally conical form which is adapted to enter the rectum. The bodyis provided at its forward end with a bead 6 to prevent its accidentaldisplacement. The rear of the body is closed by a centrally perforatedplug 7.

The head 5v is centrally perforated for the passage of fluidtherethrough and isconnected to a tube 8 extending backward `through thehollow body 3 and out through the central perforation in the plug 7. The

tube 8 has attached to it a cap 9 overhang ing the rear end of the bodyand provided with a bayonet slot 10 engaging a pin 1l on the body, so asto hold the parts in the position shown in solid lines. By turningthecap 10, however, it is possible to withdraw the head, and to place it inthe position shown in dotted linesin Fig. 2.

rPhe operation ofA the device will be'reada ily apparent. The syringeisplaced in position in the usual manner and theluidto be administered ispassed in through the central tube 8 which, in practice, is connected toa rubber tube, as shown, for the ypurpose of conducting thereto theiuid.

W'hen the requisite amount of fluid has been administered, the head isdrawn back so as toclear the entire body and connect it with the lateralextension 4. The contents of the bowels will then pass out through thebody 3 and extension 4 and into the tubing connected therewith. Ifdesired, the tube connected to the extension 4 may run to a sucSpecification of Letters Patent. "Application mea Marcil 25, 1914.`semina. 827,142.

tionchamber, so as to accelerate the evacuation. In this case thesuction may be controlled by means of a perforation 12 at the rear endof the body through which air may be admitted, when desired, or whichmay be kept closed by the fingers. If the natural expulsivemovements ofthe bowel-muscles are relied upon, this perforation may be omitted. r

The present device is particularly desirable because, by its use, it ispossible to vdispense with the use of a bed-pan in many cases, acomplete yevacuation being possible through the tube.
